BACK LASH ZEROING DEVICE FOR INPUT/OUTPUT SINGULAR HELICAL GEAR

摘要

A back lash zeroing device for an input/output singular helical gear is disclosed. The present invention comprises: a pair of helical gears composed by an assembly of a singular pinion gear and the singular ring gear divided into the drive gear and the slip gear; and an engagement structure engaged to enable the pinion gear to be engaged with the ring gear having the different number of teeth. The engagement structure, wherein the slip gear has one or more teeth then the drive gear to reduce a gap between the gears in gear-engagement of the ring gear with respect to the pinion gear, comprises an axial support unit supporting the slip gear in order to reduce the gap generated at a point where the teeth of the pinion gear and the drive gear meet.;COPYRIGHT KIPO 2016
